Pool & Spa Filter Cartridges
Every cartridge below is cross-referenced across Pleatco, Unicel, Filbur, and OEM part numbers, so you can find the right one starting from any of them. Browse by brand if you know your existing part number, or by physical size if you only have a tape measure to work with.
Browse by filter brand
Browse by OEM number
If the number you have came off the cartridge your tub or pool shipped with, it is an OEM number and it belongs to the equipment builder rather than the filter maker. Look it up to find the aftermarket cartridges that fit the same housing.

Helpful when the part number on your old cartridge is rubbed off but a tape measure isn't. Outer diameter and length are the two numbers that matter.
